Query a modem's Eb/No, BER, and Level
Query Response
Bytes 1 - 2 = Binary value Raw BER
Bytes 1 - 2 = Binary value corrected BER
Binary value, 1 decimal point implied
Byte 3 = Binary value exponent
Byte 3 = Binary value exponent
Bit0 = Raw BER and corrected BER status. 1 = Valid
Bit1 = Test 2047 BER status. 1 = Valid
Bits 2 – 3 = EbNo status, 0 = EbNo is invalid
1 = EbNo is valid, 2 = EbNo is smaller than indicated
value, 3 = EbNo is greater than indicated value
Bit 4 = BER Counter Overflow.
1 = Overflow Condition
Bit 5 = Test 2047 BER Counter Overflow
1 = Overfl ow Condition
Bits 6 – 7 = Reserved
